[build] bjam in boost/tools/build/v2/test doesn't work
by Jim Bell 22 Nov '10

22 Nov '10

Running bjam in boost/tools/build/v2/test doesn't (seem to) run build's regressions. Instead, I get: jamfile.jam:8: in modules.load rule project-root unknown in module Jamfile</F:/tmp/boost-MinGW-32/trunk/boost/t ools/build/v2/test>. F:/tmp/boost-MinGW-32/trunk/boost/tools/build/v2/build\project.jam:314: in load-jamfile F:/tmp/boost-MinGW-32/trunk/boost/tools/build/v2/build\project.jam:62: in load F:/tmp/boost-MinGW-32/trunk/boost/tools/build/v2/build\project.jam:168: in project.find F:/tmp/boost-MinGW-32/trunk/boost/tools/build/v2\build-system.jam:569: in load F:\tmp\boost-MinGW-32\trunk\boost\tools\build\v2\test\..\kernel\modules.jam:283: in import F:\tmp\boost-MinGW-32\trunk\boost\tools\build\v2\test\..\kernel\bootstrap.jam:14 2: in boost-build F:\tmp\boost-MinGW-32\trunk\boost\tools\build\v2\test\boost-build.jam:14: in module scope If I run "python absolute_sources.py" (to pick that test as an example), I get very little (and it doesn't match regression test output): F:\tmp\boost-MinGW-32\trunk\boost\tools\build\v2\test\TestCmd.py:60: Deprecation Warning: The popen2 module is deprecated. Use the subprocess module. import popen2 Am I close? I realize that build is a different animal. Are there instructions for running its tests in isolation? (Could those instructions be put in boost/tools/build/v2/index.html?) If you're reading this on the boost-build list, please CC me as I'm not subscribed. Thanks, -Jim PS: My apologies if I missed a response to this. I posted it last week on boost.

[accumulators] serialization support
by Zoran Angelov 22 Nov '10

22 Nov '10

Hi, Have anyone considered for boost.accumulators having a serialization support? It will be helpful for example in situations where data is being accumulated/sampled on long time intervals, and persistence of boost.accumulators objects is impossible. Something like this: boost/accumulators/statistics/count.hpp: . . . template<typename Sample, typename Tag> struct immediate_mean_impl : accumulator_base { // for boost::result_of typedef typename numeric::functional::average<Sample, std::size_t>::result_type result_type; template<typename Args> immediate_mean_impl(Args const &args) : mean(numeric::average(args[sample | Sample()], numeric::one<std::size_t>::value)) { } template<typename Args> void operator ()(Args const &args) { std::size_t cnt = count(args); this->mean = numeric::average( (this->mean * (cnt - 1)) + args[parameter::keyword<Tag>::get()] , cnt ); } result_type result(dont_care) const { return this->mean; } template <typename Archive> void serialize(Archive &ar, const unsigned int version) { ar & BOOST_SERIALIZATION_NVP(mean); } private: result_type mean; }; . . . The problem is that members, storing the state are private. Thanks

[1.45][signals2] Can't build PDF docs?
by John Maddock 21 Nov '10

21 Nov '10

I'm trying to build the signals2 docs for the PDF doc distribution, but I'm failing with: warning: failed to load external entity "hello_world_def_code_snippet.xml" tutorial.xml:50: element include: XInclude error : could not load hello_world_def_code_snippet.xml, and no fallback was found warning: failed to load external entity "hello_world_single_code_snippet.xml" tutorial.xml:52: element include: XInclude error : could not load hello_world_single_code_snippet.xml, and no fallback was found warning: failed to load external entity "hello_def_code_snippet.xml" tutorial.xml:63: element include: XInclude error : could not load hello_def_code_snippet.xml, and no fallback was found etc... I can see that process_snippets.exe is being invoked, but I can't find the output xml files anywhere. This occurs if I either build from within the doc/pdf directory, or the libs/signals2/doc directory. Any ideas? Thanks, John.

[Guild] Recruiting & Instructions, rough first draft
by Jim Bell 20 Nov '10

20 Nov '10

Here's some writing I threw down a little while ago. Please comment, here or privately. Copy my text for reference. It's on my website partly because I've done some formatting (emphasizing), as you'll see. It's rough, and lacks some crucial detail. http://jc-bell.com/contributions/boost-guild/boost-guild-recruit http://jc-bell.com/contributions/boost-guild/boost-ticket-handling http://jc-bell.com/contributions/boost-guild/boost-regression-troubleshooti… Cheers! -Jim

The cpp-netlib Release 0.8 is Out Now!
by Dean Michael Berris 19 Nov '10

19 Nov '10

Hi Everyone, advanced apologies for the cross-post. To those interested and watching the cpp-netlib project's progress, this afternoon Philippine time I just packaged and released the latest installment of the cpp-netlib project. Release 0.8 features: * An asynchronous HTTP server template, supporting asynchronous handler invocation and asynchronous writing to the established HTTP connection on the handler side. An example of one use for this is included in the library which implements a simple static web server, benchmarked with Apache AB on a dual core Intel Core 2 CPU with 2GB RAM to be able to serve a 10kb file at 4700 requests per second on 64-bit Linux 2.6.36. You can find out more about the example here: http://goo.gl/5mVuY * More in-depth documentation covering the HTTP Client and Server APIs, now hosted online as well. Read the documentation at http://cpp-netlib.github.com/0.8/ * A simple thread pool implementation that uses Boost.Asio underneath, with a simple API for posting nullary function objects as tasks. The number of threads to run is configurable as a constructor parameter -- this is especially required by the asynchronous HTTP server template, where handlers are queued to be executed. The library is released under the Boost Software License, and is being developed for future submission to the Boost C++ Library. You can download the latest and previous releases from http://github.com/cpp-netlib/cpp-netlib/downloads. Have a great day everyone and I look forward to your very valuable feedback! -- Dean Michael Berris deanberris.com

Boost bug sprint?
by Marshall Clow 19 Nov '10

19 Nov '10

Since we're now at November 13th, and I originally proposed starting the bug sprint "after the 1.45" release, and "On November 15th", I think that something's gotta give. So, I'm proposing that we start the bug sprint on Saturday, November 27th, and run through Sunday, December 5th (9 days, two weekends, one work week). That way people who work on boost as part of their day jobs will have a full week to participate, while those who do "nights and weekends" will have plenty of time as well. What does everyone think? -- Marshall

LLVM license compatibility with BSL
by vicente.botet 19 Nov '10

19 Nov '10

Hi, I have found quite useful to adapt the test for llvm/libc++ ratio/chrono to test Boost.Ratio and Boost.Chrono. But Anthony has signaled me that maybe there is a compatibility problem with the license included in these files. //===----------------------------------------------------------------------===// // // The LLVM Compiler Infrastructure // // This file is distributed under the University of Illinois Open Source // License. See LICENSE.TXT for details. // //===----------------------------------------------------------------------===// Is the LLVM License (http://llvm.org/docs/DeveloperPolicy.html#license) compatible with the Boost Software License? Can we include files with this comment on a Boost library? Best, _____________________ Vicente Juan Botet Escribá http://viboes.blogspot.com/
